LATIN NAME OF THE GENUS AND SPECIES OF THE PLANT CLAIMED

Prunus persica L. Batsch.

VARIETY DENOMINATION

‘SWEETREINE’.

BACKGROUND OF THE NEW VARIETY

The present invention relates to a new and distinct variety of white peach tree, Prunus persica L. Batsch, which has been given the variety denomination ‘SWEETREINE’. This new tree produces fruit with a long shelf life without alteration both on the tree after growth completion and after harvesting, large fruit with very good eating quality, flesh fruit for fresh market in early August in the Pyrénées-Orientales department, France. Contrast is made to ‘MAPERLA’ (non-patented), ‘SWEETSTAR’ (Plant patent application Ser. No. 12/382,126) peach trees, standard varieties, for reliable description. ‘SWEETREINE’ is a promising candidate for commercial success in that it has a semi-late period flowering, fruit with very long shelf life without alteration after harvesting, and so a very durable fruit.

ORIGIN OF THE VARIETY

‘SWEETREINE’ peach tree originated in a cultivated area of the south of France, in the Pyrénées-Orientales department, where it was tested. The male parent is ‘NECTACHIEF’ (U.S. Plant Pat. No. 19,330), yellow nectarine tree with a very attractive fruit of a round shape and a bright red blush color. The female parent ‘MASNOW’ (non-patented) is a white peach tree with a well-balanced flavor. ‘NECTACHIEF’ (U.S. Plant Pat. No. 19,330) was obtained by seedling. The male parent is ‘ZAITABO’ (Big Top®) nectarine tree and the female parent is ‘ARMKING’ (U.S. Plant Pat. No. 2,943) nectarine tree. ‘NECTACHIEF’ (U.S. Plant Pat. No. 19,330) blooms in March in South of France. More particularly, it blooms at the same time as ‘NECTAROSS’ or ‘MAILLARMATE’, and 3 days after ‘ZAITABO’ (Big Top®) between the 7^(th) and 21^(st) of March. The first fruit of ‘NECTACHIEF’ (U.S. Plant Pat. No. 19,330) ripens in early July, approximately 6 days after ‘ZAITABO’ (Big Top®). More particularly, it approximately ripens between the 4^(th) and 13^(th) of June. ‘MASNOW’ (non-patented) is a white peach variety with a very good presentation and a well-balanced flavor. The blooming period begins in mid-March and the maturity period begins usually in late July in the South of France climatic conditions. It has been determined to have unique tree and fruit characteristics making it worthy for commercial fresh fruit production. There are no known effects of this standard rootstock on this scion cultivar. Asexually propagated plants remained true to the original tree and all characteristics of the tree and the fruit were transmitted. The plant was reproduced asexually in Elne, Pyrénées-Orientales department, France.

SUMMARY OF THE VARIETY

The new and distinct variety of white peach tree ‘SWEETREINE’ blooms in early March near Elne in the Pyrénées-Orientales department, France. The flowering period is considered as semi-late in the South of France.

The first fruit of ‘SWEETREINE’ ripens in early August, around 2.5 weeks later than ‘SWEETLOVE’ (Plant patent application Ser. No. 12/382,096) variety or 2 weeks before ‘SWEETSTAR’ (Plant patent application Ser. No 12/382,126) variety. More particularly it ripens between the 2^(nd) of August and the 11^(th) of August.

DETAILED BOTANICAL DESCRIPTION

The tree, flowers, and fruit may vary in slight detail due to variations in soil type, cultural practices, and climatic condition. The potential for commercial production of fresh fruit by ‘SWEETREINE’ is high, due to fruit very long shelf life without alteration after harvesting.

Trees are vigorous and large stature half-standing in a semi-spread to semi-upright aspect. The flowering shoot is present excluding brushwood side away from sun. Flowering begins semi-late in springtime. The type of flower is showy, with medium to large petal size. Petals are medium pink. Leaf glands are present and reniform. Time of maturity for consumption is considered semi-early. The fruit flesh is white with a slight red pigmentation under the skin and around the stone cavity. Fruit skin is very thick, of bright purple red color on a washed-pink red ground. The stone is of medium size and the flesh is very adherent. Fruit taste is semi-sweet.

Compared to ‘MAPERLA’ (non-patented) the fruit flavor is semi-sweet. The blooming period is earlier of approximately 6 days than ‘MAPERLA’ (non-patented). The maturity period is semi-early in South of France and considered as identical.

Compared to ‘SWEETLOVE’ (Plant patent application Ser. No. 12/382,096) the maturity period is later of 2.5 weeks or earlier of 2 weeks than ‘SWEETSTAR’ (Plant patent application Ser. No. 12/382,126).

DETAILED DESCRIPTION

Referring more specifically to the pomological details of this new and distinct variety of white peach tree, the following has been observed during the second fruiting season under the ecological conditions prevailing at the orchards located near the town of Elne, in the Pyrénées-Orientales department, France. All observations have been made on rootstock cultivar. The rootstock was a ‘Franc Inra Montclar®’ tree. All major color code designations are by reference to The R.H.S. Color Chart (Fourth Edition) provided by The Royal Horticultural Society of Great Britain.

-   Tree:     -   -   Size.—Medium to high as compared to other common commercial             peach cultivars. The tree size the first year was             approximately 2.50 meters. The tree was pruned during each             following dormant season to a height of approximately 2.50             meters. Current seasons shoots growth could reach 0.80             meters. So the tree size from the second year (second and             next years) reached a final height of 3.30 meters with             current seasons shots length comprised.         -   Spread.—Approximately 1.0 meter. The whole orchard was             oriented to a central leader organization, with tree lines             spaced of 4.0 meters and trees spaced of 1.0 meter in a same             tree line.         -   Vigor.—Vigorous. The present variety grew from about 60.0             centimeters to 80.0 centimeters in height during the first             and following growing seasons. For second and following             seasons, the variety was pruned to an approximate height of             2.50 meters.         -   Productivity.—Very productive. Fruit set is spaced by             thinning to develop the remaining fruit into the desired             market sized fruit. The number of the fruit set varies with             the prevailing climatic conditions and cultivar practices             employed during the bloom period, and is therefore not             distinctive of the present variety.         -   Bearer.—Considered very regular. A thinning of 1 fruits on 3             was necessary for the tree valorization. Thinning may not be             too important because of the high magnifying potential of             the fruit.         -   Form.—Semi-spread to semi-upright naturally.         -   Density.—Considered medium dense to dense.         -   Hardiness.—The present tree was grown and evaluated in             France. The variety appears to be hardy under typical             central Pyrénées-Orientales department climatic conditions.             Fruits remain very attractive because they are well colored             with an excellent semi-sweet flavor. Experimentations on             different sites with winter chilling requirement comprised             between 350 hours and 1200 hours showed a good behavior of             the tree in all cases. No damages were caused by ascertained             temperatures as low as −12° degrees Celsius. The tree was             also very resistant to frosty springtime weather. -   Trunk:     -   -   Diameter.—Approximately between 5.5 centimeters and 6.5             centimeters when measured at a distance of approximately             30.0 centimeters above the soil, on trees from the second             growing season.         -   Bark texture.—Rough, with lenticels.         -   Lenticels.—Numerous lenticels are present on trees from the             second growing season. The lenticels range in size from             approximately 0.15 centimeters in height and about 0.2 to             0.4 centimeters in width.         -   Lentical color.—The outside surface of lenticels has a             silver-grey color (RHS GREY 201 C), whereas the inside             surface is brown (RHS GREYED ORANGE 166 C-D).         -   Bark coloration.—The bark has a silver-grey color a little             more pronounced than lenticels outside color (RHS GREY 201             B-C to RHS BLACK N200C). -   Branches:     -   -   Size.—Mature branches and current season shoots are             considered medium to thick for the variety.         -   Diameter.—Average as compared to other peach varieties. The             current season shoots have a diameter from 4.0 to 10.0             millimeters, and branches of trees from the second growing             season have a diameter comprised between 12.0 and 20.0             millimeters.         -   Current season shoots surface texture.—Average, wood that is             several years old has no furrowed appearance.         -   Crotch angles.—Primary branches are considered variable, but             the crotch angles are generally between 60 degrees and 85             degrees from the horizontal axis. This particular             characteristic is not considered distinctive of the variety,             however.         -   Internode length.—Generally 25.0 millimeters to 30.0             millimeters.         -   Color of mature branches.—Brown (RHS GREY BROWN 199 A-B).         -   Color of current season shoots.—The color of new shoot tips             is considered a pale yellow green (RHS YELLOW GREEN 144 A-C)             on lower part of new shoot tips, whereas the upper part is             colored brown-purple to brown-red (RHS GREYED PURPLE GROUP             187 A-B to GREYED RED 182 A) following the position on the             shoot. -   Leaves:     -   -   Size.—Considered medium to large for the species. Leaf             measurements have been taken from vigorous, upright,             current-season growth at approximately mid-shoot. The ratio             leaf length/leaf width is above 3.72.         -   Leaf length.—From 161.0 to 178.0 millimeters with leaf             petiole. Average length of 164.0 millimeters.         -   Leaf width.—From 39.0 to 51.0 millimeters. Average width of             44.0 millimeters.         -   Leaf base shape.—Concave relative to the leaf longitudinal             axis.         -   Leaf form.—Lanceolate.         -   Tip form.—Acuminate and small. -   Leaf color:     -   -   Upper leaf surface.—Dark green (RHS GREEN 137 A).         -   Lower surface.—Of a lighter green (RHS GREEN 137 B-C) than             the upper leaf surface color.         -   Leaf texture.—Smooth and glabrous.         -   Leaf venation.—Pinnately veined. -   Mid-vein:     -   -   Color.—Light green with a yellow touch (RHS YELLOW GREEN 145             C-D) and evolves with maturity.         -   Leaf margins.—Slightly undulating.         -   Form.—Considered slightly dentate.         -   Uniformity.—Leaves are isolated or grouped by 2 or 3. In             this last case, it is found one leaf of normal size with one             or two smaller leaves (size-reduction of 50% and more). -   Leaf petioles:     -   -   Size.—Considered medium.         -   Length.—About 9.0 to 11.0 millimeters.         -   Diameter.—About 1.7 millimeters.         -   Color.—Light green on the upper surface (RHS YELLOW GREEN             144 A-B) and light green (RHS YELLOW GREEN 145 B) on the             lower surface. -   Leaf glands:     -   -   Size.—Considered medium. Their length is about 1.5             millimeters.         -   Number.—Generally 3 to 4.         -   Type.—Reniform.         -   Color.—On young leaves, leaf glands color is considered pale             green (RHS YELLOW GREEN 145 B). On older leaves, leaf glands             color turn to a dark brown (RHS GREY BROWN 199 A-B). -   Leaf stipules:     -   -   Generally.—No leaf stipules were observed. But as seen in             the characteristic relative to the leaves uniformity, it is             possible to find leaves by groups of 2 or 3, with a             normal-size leaf and smaller ones. -   Flowers: -   Flower buds:     -   -   Generally.—At pre-floral stage of development, the floral             buds are conic in form with a round tip. Their form is             evolving until blooming, with variables dimensions. Just             before blooming, floral buds are approximately 12.0             millimeters wide and approximately 20.0 millimeters long.         -   Color.—This characteristic is dependent upon the proximity             to bloom. At pre-floral stage of development, the bottom of             the flowers buds, or calyx formed by sepals, is of             purple-brown color (RHS GREYED PURPLE 183 A-B); the corolla             formed by petals, is generally of medium pink color (RHS RED             PURPLE 65 A-B to RED PURPLE 69 B). Petals color shows an             evolution until the end of blooming.         -   Hardiness.—The buds are considered hardy under typical             central Pyrénées-Orientales department climatic conditions.             No winter injury was noted during the last several years of             evaluation in the central Pyrénées-Orientales department,             with winter temperatures as low as −10° C. in January. The             current variety has not been intentionally subjected to             drought or heat stress, but the variety showed a very good             resistance in orchard to temperatures up to 42° C. with an             average temperature between 28° C. and 30° C. during 3 weeks             in summer.         -   Date of bloom.—Generally early March. The first bloom was             observed on Mar. 1, 2005. Second to fourth blooms took place             respectively on Feb. 28, 2008, Mar. 1, 2009 and Mar. 22,             2010.         -   Blooming time.—Considered semi-late in relative comparison             to other commercial peach cultivars grown in the             Pyrénées-Orientales department, France. The date of full             bloom is observed at the middle of the blooming period. The             date of bloom varies slightly with climatic conditions and             cultural practices.         -   Duration of bloom.—Approximately 7 to 9 days. This             characteristic varies slightly with the prevailing climatic             conditions.         -   Flower type.—The variety is considered to have a showy type             flower.         -   Flower size.—Considered medium to large. Flower diameter at             full bloom is approximately 32.0 to 36.0 millimeters.         -   Bloom quantity.—Considered abundant, approximately 40             flowers per meter.         -   Flower bud frequency.—Generally 2 flower buds appear per             node, occasionally 1. -   Petal:     -   -   Size.—Considered medium to large for the species.         -   Length.—Generally about 19.0 millimeters.         -   Width.—Generally about 19.0 millimeters.         -   Petal form.—Round.         -   Petal count.—Nearly always 5.         -   Petal texture.—Smooth.         -   Petal color.—Medium pink (RHS RED PURPLE 65 B-D) when young,             darkening with advancing senescence.         -   Fragrance.—Soft. -   Petal claw:     -   -   Form.—The claw is considered to have a conic form with a             slightly rounded tip.         -   Length.—Approximately 6.0 to 8.0 millimeters.         -   Width.—Approximately 5.0 to 6.0 millimeters.         -   Petal margins.—Slightly undulating. -   Petal apex:     -   -   Generally.—The petal apices are generally complete at the             tip and round. -   Flower pedicel:     -   -   Length.—Considered medium to long and having an average             length of approximately 3.0 to 5.0 millimeters.         -   Diameter.—Average 2.0 millimeters.         -   Color.—Brown to light brown (RHS GREY BROWN N199 B-C). -   Calyx:     -   -   Internal surface texture.—Smooth and glabrous.         -   Color.—The inner surface of the calyx is considered of             washed-green yellow (RHS YELLOW 13 A-B to YELLOW GREEN 150             A-B) color. The outer surface is purple brown (RHS GREYED             PURPLE 183 A-D). -   Sepals:     -   -   Surface texture.—The outer surface has a fine pubescent             texture.         -   Size.—Medium.

The flavor is considered juicy and             aromatic.         -   Juice.—Very juicy at complete maturity.         -   Brix.—Superior to 13.0 degrees. This characteristic varies             slightly with the number of fruit per tree; prevailing             cultural practices; and the surrounding climatic conditions.         -   Flesh color.—White flesh (RHS WHITE 155 A-B) usually with a             slight red pigmentation (RHS RED 53 B-C) in the stone cavity             and star-shaped around the stone cavity on approximately 5.0             millimeters. -   Stone:     -   -   Type.—Clingstone, more or less intense according to the             fruit maturity.         -   Stone cavity.—Medium, with an ovoid form and dimensions             corresponding to the stone's dimensions.         -   Size.—Considered medium for the variety. The stone size             varies significantly depending upon the tree vigor, crop             load and prevailing growing conditions.         -   Length.—From 30.0 to 33.0 millimeters.         -   Width.—From 24.0 to 27.0 millimeters.         -   Diameter.—From 17.0 to 21.0 millimeters.         -   Form.—Elliptic.         -   Base.—Straight. -   Apex:     -   -   Shape.—The stone apex is short and prominent. -   Stone surface:     -   -   Surface texture.—The pit is transversely furrowed on its             entire surface. Furrows are more pronounced toward the apex.             The stone is pitted toward the base. Relief is prominent             generally and present basally.         -   Ridges.—The surface texture is generally characterized by             more prominent ridges along the ventral edges and is more             prominent at the apical tip. -   Ventral edge:     -   -   Width.—Considered small to medium, and having a dimension of             approximately 2.0 millimeters at mid-suture. -   Dorsal edge:     -   -   Shape.—Grooved.         -   Stone color.—The color of the dry stone is purple brown (RHS             GREYED PURPLE N186 C to 187 A-B) with some zones of light             brown (RHS GREYED ORANGE 174 B-C).         -   Tendency to split.—Splitting is absent or very low,             depending on climatic conditions between blooming period and             stone hardening. -   Kernel:     -   -   Size.—Medium.         -   Length.—About 17.0 millimeters.         -   Width.—About 13.0 millimeters.         -   Thickness.—About 5.0 to 6.0 millimeters.         -   Form.—Considered oblate and elliptic.         -   Pellicle.—Slightly pubescent.         -   Color.—The kernel skin is orange brown (RHS GREYED ORANGE             164 A-B to 165 B). The almond is cream-white (RHS WHITE 155             B). The kernel and its embryo are mature at the time of             fruit maturity.         -   Use.—The subject variety ‘SWEETREINE’ is considered to be a             white peach tree of the semi-early season of maturity, and             which produces fruits that are considered large, firm, and             attractively colored. Fruits are excellent for uncooked             consumption, crunchy or at full maturity. Due to their flesh             quality, firmness and density, they can also be             commercialized as 4^(th) range product (packed fruit or             fruit in bags for example). And they are also useful for             both local and very long distance shipping.         -   Keeping quality.—Excellent. Fruit stayed a little more than             one week on tree before harvest and then, has stored well             more than 4 weeks after harvest at 2.0 degree Celsius. They             have a slow maturation and a long shelf life both on the             tree after growth completion and after harvesting without             alteration.         -   Shipping quality.—Considered very good. The fruit of the new             peach variety showed minimal bruising of the flesh or skin             damage after being subjected to normal harvesting and             packing procedures. Its resistance to handling during             harvest and packing and its long shelf life without             alteration after harvest easily permit 3 weeks — shipping at             2° degree Celsius.         -   Resistance to insects and disease.—No particular             susceptibilities were noted. The present variety is low             sensitive to powdery mildew, and low sensitive to             conservation diseases and decay due to its thick and strong             skin. -   Although the new variety of peach tree possesses the described     characteristics when grown under the ecological conditions     prevailing near Elne, Pyrénées-Orientales department, France, it     should be understood that variations of the usual magnitude and     characteristics incident to changes in growing conditions,     fertilization, pruning, pest control and horticultural management     are to be expected.
